Abstract
A surgical instrument includes a housing, an end effector assembly, and a shaft. The end effector assembly includes first and second jaw members each defining a curved configuration. At least one of the jaw members is movable relative to the other between a spaced-apart position and an approximated position. The shaft includes a proximal portion coupled with and extending distally from the housing and a distal portion extending distally from the proximal portion and having the end effector assembly coupled thereto at the distal end thereof. The proximal portion defines a circular cross-sectional configuration to facilitate formation of a fluid-tight seal thereabout. The distal portion defines a rectangular cross-sectional configuration configured to facilitate insertion through a cannula.
